BALL-BEARING.

SPECIFICATION forming part of Letters Patent No. 653,184, dated July 3,1900. Application filed February 3 1900. Serial No. 3,798. (No model.)

To aZZ whom it may concern:

Be it known that I, ELI SAMUEL REED, a citizen of the United States,residing at Hill City, in the county of Hamilton and State of Tennessee,have invented certain new and useful Improvements in Ball-Bearings, of

which the following is a specification.

This invention relates to an improvement in ball-bearings so arrangedand applied in connection with the shafts or other parts of themachinery that the speed of the latter may be increased and efiicientaction'augmented; and the invention therefore consists, essentially, inthe construction, arrangement, and combination of parts, substantiallyas will be'hereinafter described and claimed.

The drawing illustrates a vertical section of the ball-bearing.

Like letters of reference designate like parts in the figure of thedrawing.

G designates the band-wheel, from which passes the belt that operatesthe sewing or other machine. The pitman H is driven by the treadle andis in turn directly connected to the crank I,which it actuates.

J designates a short shaft to which the gearwheel K is keyed. This shaftJ is supported horizontally in the casing D, which has its parallelvertical sides formed with enlargements D D to receive the shells L,which fit neatly therein, the same being rounded and cup-shaped andperforated concentrically, with openings in the casing sides, so thatthe shaft J may lie loosely therein. Observing now more particularly theshaft J, it will be seen that the right-hand end thereof isscrewthreaded at g. On this end g is a nut g, screwed thereon andholding a series of balls between it and its ball-bearingshell L. Alsoon end 9 is a dustcap M, the edge of which surrounds the edge of shell Land prevents the entrance of dust thereinto. Also there is a lock-nut 9which clamps the dust-cap firmly in place over the nut g. It will be observed that the dust-cap M is reversely cupshaped from the shape ofshell L. On the other end of shaft J is a sleeve 9", diifering from thenut 9 only in not being internally threaded. This sleeve 9 holds acircular series of balls between itself and the inverted shell L. Nextto the sleeve 9 is another dust-cap M, and at this end of the shaft J isa pin R for attaching the hub of crank-arm I to the shaft J. Thus itwill be seen that the shaft J is mounted in ball-bearings and is heldsecurely in such a fashion that it will rotate very easily.

Parallel to shaft J is another shaft J, to which the pinion K is keyed.Pinion K meshes with gear-wheel K. J is supported horizontally in thebosses D D formed on the sides of easing D. The ball-bearing for shaft Jis substantially the same as that for shaft J. On shaft J istheband-wheel G.- The end of the shaft J is engaged by the center pin 0,that passes through the table or other support and serves to steady thewheel G.

What I claim is- The herein-described ball-bearing, comprising the shafthaving the screw-threaded end g, nut g screwed thereon, the shell L alsoon said end g, a seriesof balls between the nut g and the shell L, thedust-cap M having its edge surrounding the edge of shell L so as toprevent the entrance of dust thereinto, a lock-nut g clamping thedust-cap M firmly in place upon the nut g, the sleeve 9 located on theother end of the shaft, and having a smooth non-threaded interior, ashell L and dust-cap M likewise on said end of shaft J, together with acircular series of balls between sleeve g and shell M, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.

ELI SAMUEL REED.
